Chapter 397 Tunnel Exploration
After seeing off the forest ranger, Liang En and the others quickly had a discussion, because the current situation was different from what they had imagined before, and they needed to adjust the plan to adapt to the current situation.
However, after a few minutes of brief discussion, they still chose to continue the search work. After all, they were already here, and they would always feel a little bit unwilling not to go to the target point to take a look.
More importantly, more than 70 years have passed, and some things that may not have been valuable back then may have greatly improved their value, so there may be more valuable things in the cave.
After arriving at the top of the mountain, Liang En immediately activated the [Eye of Daedalus (SR)] and added 10 destiny points. In an instant, he roughly understood the interior of the entire mountain near his position structure.
Judging from the detection results, the construction quality of the tunnel built by the Germans was indeed good. At least now it seems that the overall structure remains intact, only a little bit of the entrance collapsed due to the blasting.
At the same time, because of the effectiveness of the card, Liang En easily found the ventilation duct of this underground fortification.Then he took Joan of Arc and Fan Meng to the entrance where the ventilation pipe was buried and dug it up.
As their shovels removed the surface dirt and cleared away a row of wooden boards that had clearly been purposely blocked, a ventilation pipe entrance that had been hidden under the earth and rocks was exposed.
Judging from the existing appearance, the shape of this vent looks like a small house with air leakage everywhere, with four pillars and a roof, which should prevent backflow in rainy and snowy weather.
After a brief inspection, they determined through the traces of bolts on the pillars and the ground that there should have been metal shutters between the pillars, but they didn't know who removed them later.
Because of the clearing of the obstructions, puffs of white smoke rose from the bottom of the ventilation pipe, bringing a damp and rotten smell. Obviously, this was formed when the high-temperature underground air met the damp and cold air above.
After checking with flashlights, they found that, like all large ventilation ducts, there were inverted U-shaped steel ladders on the walls for people to enter and exit.
Although judging from these places near the entrance of the cave, these steel bars that have been preserved for more than 70 years should still be usable, but the situation underneath is not easy to say, so it is best to hang them slowly with ropes.
Anyway, whether it was the inspection just now or Liang En's card detection, he could confirm that the vertical drop of this place was less than 25m, and the climbing rope they brought could safely send people to the bottom of this ventilation duct.
Considering the possible poisonous and harmful gases and the lack of oxygen in the confined space, Liang En and the others did not plan to go down now, but went to the car to drag some of the large items prepared earlier with a ski.
So at 10:30 noon, they were finally ready to build a hollow steel frame at the entrance of the cave, and then used the safety rope on the pulley block operator Fan Meng who was hanging on the frame to let Fan Meng get out of the ventilation duct a little bit. up and down.
"Everything is normal, and these steel ladders can also be used." After descending to the bottom, Fan Meng, carrying a small oxygen tank on his back, said through the walkie-talkie. Considering that there is no equipment at hand to determine whether the air is safe, this is a necessary insurance facility.
However, unlike the oxygen cylinders used for medical treatment or diving, the one-liter oxygen cylinders they carried could only be used for one hour, but they were relatively lighter, at least for Liang En and the others, it did not affect their movements.
After confirming that it was safe below, Liang En nodded to Joan of Arc who was staying above, and then went down the pipe in the same way to the ventilation room at the bottom of the ventilation pipe.
Although the inner wall of the cement is a little weathered, and the steel bars are covered with rust, but I have to say that the quality of the German engineering is unmatched. Over the past few decades, the rebar steps have not loosened at all.
"How's the situation outside?" Liang En asked Fan Meng who was searching outside the door with a bright flashlight while removing the safety rope from his body.
"This should be a north-south thing. The south entrance should be the only one, but it has been blocked by blasting. At least 20 meters to the north are tunnels with railway tracks. I can't see what's inside?"
"Then let's go north—" Liang En made a decision immediately, and then he and Fan Meng checked each other's fully enclosed chemical protective suits, placed the signal repeater, and walked north together.
According to the direction of this tunnel, this should be a tunnel connecting Austria and Germany.The rails and sleepers in the tunnel are still there, and there is water seepage in some places, but the amount is not large, and the overall appearance is complete.
After scanning the surroundings with a flashlight, Liang En found that the tunnel was a half-finished product. In some places there were traces of steel reinforcement and concrete reinforcement, but in most places there were only bare rocks.
Fortunately, judging from the thin layer of dust on the ground, the quality of the entire tunnel is good, and there is no possibility of collapse in a short period of time. At the same time, all the overly protruding rocks have obviously been artificially leveled.
Just after they walked more than ten meters, they suddenly saw a plane on the side of the tunnel that was purposely flattened. A double-headed eagle with a crown on its head and a coat of arms on its chest was engraved on it, and a line of German was written below it.
"Military Emergency Railway, Austro-Hungarian Empire, 1916." Soon, Liang En translated the German content. "It seems that this should be a military railway tunnel built by the Austro-Hungarian Empire during World War I, and it should be planned to lead to Germany."
This also explains why the sleepers in the tunnel are made of wood, because the railway was built too early, and around the 20s, people would use cement as the sleepers for the rails in the tunnel to reduce the erosion of moisture in the tunnel .
Continuing forward, the tunnel began to bend slightly to the east and diverged into several forks. After looking at several forks, Liang En immediately decided to go to the leftmost fork first. This time he walked less than 20m. The tunnel is no longer empty.
"Train carriage!" Liang En recognized the truck carriage parked on the track at first glance, and at the same time, a series of stories about Spicy Crunch hidden treasures or golden trains popped up in his mind.
The first time they saw the train, Liang En and the others took out the metal detector and began to detect the surroundings to prevent any explosives or traps around the train.
However, after spending 10 minutes exploring, they found that there was nothing around. This may be because the Germans did not install it back then, or it may be that the Americans cleaned up those things later.
Considering that there will not be any dangerous creatures in this sealed place for a long time, and both of them have received professional training in search, they agreed to meet in the ventilation room just half an hour later after checking their watches, and then started Search separately.
Because they needed to check whether there were dangerous goods, the search process couldn't be fast at all, so when they met in half an hour, they only had a simple understanding of the underground situation.
Taking advantage of the opportunity of changing the oxygen cylinder, Fan Meng told Liang En about what he had just discovered. After combining Fan Meng's description and his own discovery, Liang En finally had a comprehensive understanding of this underground building.
